I just bought an 86 js550 for 150 bucks. I took the entire engine apart and found that it is in bad shape, i think the previous owner didn't know what he was doing and hydrolocked it. Everything inside is pretty rusty and dirty, but it doesnt seem like theres any significant damage. Can i still save the ski? Im worried about the crank, is there a special way to clean it up, i just wanna buy new bearings and seals? Do people repair hydrolocked skis a lot? And the cylinder walls don't look to bad, looks like they need to be honed out. Any advice, please.
